Purinton, Waterbury; Conn., assignor to The Patent Button Company, Waterbury, Conn., a corporation of Connecticut Original application March 17, 1941, Serial No. 'l 383,813. Divided and this application March 27, 1941, Serial N0. 385,553 l claims. (ci. zi-zos) 'My inventionrelates to new and useful improvements in snap fasteners, and is a division ofthe application led. by me on March 17, 1941, Serial Number 383,813, for Snap fasteners.

The present invention relates to what is known as a clampingk member or ring, and has for an object to provide a means to receive and hold the prongs of the socket member of thesnap fastener when the said socket is attached to its cloth.

Another object of the'invention is to provide the ring or clamping member to which, and form-k ing part' thereof,is molded a plastic, such as plaskonfy which may be of any desired color so. as to harmonize with the garment to which, the snap fastener is to be attached.

Another object of the invention is to provide the ring of the socketmember of the snap fastener with means for receiving the attaching prongs of the socket member and supporting a head formed of Plaskon, which is so anchoredin the said ring that there is no possibilitxr of the same ever becoming accidentally removed therefrom.

Still another object of the invention is to provide a ring member for a snap fastener which will not only receive and tightly hold the prongs of the socket member, but will also provide a very pleasing and harmonizing appearance for the garment to which the ring is attached and further will prevent the cloth or fabric from stretching during the attaching operation.

With these and other objects in view, the invention consists in certain new and novel arrangements and combination of parts, as will be hereinafter more fully described and pointed out in the claims. y

Referring now to the drawing showing a preferred embodiment,

Fig. 1 is a sectional view of the metal ring;

Fig. 2 is a similar view but showing the Plaskon head or top molded in place;

Fig. 3 is a top plan view of the ring with its embedded Plaskon, a part being broken away for the sake of clearness of illustration;

Fig. 4 is a bottom plan view thereof; and

Fig. 5 is a sectional view of the ring with the socket member in its attached position, the dotted lines showing the socket before being clamped by the ring.

Referring now more specifically to the drawing and for the moment to Fig. 1, there may be seen the metal ring I preferably formed of brass having the overhanging and downwardly extending Wall 2 and the outwardly extending peripheral rim 3, which latter terminates short of the inner surface of the overhanging wall 2. This overhanging wall 2 and the peripheral rim 3 are integral with the body 4 of the ring.

There may also be seen the inner peripheral bead 5, the purpose of which Vis to be shortly explained. 1

Rather than having a conventional openring, I provide a plasticinsert or head 6, which may be clearly seen in Fig. 2. j Preferably this is a urea formaldehyde composition, such, as Plaskon, and may be translucent or Yopaque andv may be of diiferent colors Ato harmonize with the garment'to which it is torbe secured; A Y

It might be mentioned here that Plaskon has a" high water absorption factor and a half-inch disk may shrink as -much vas fifteen thousandths of an inch. However, by forming the mold (not shown) so that the Plaskon disk 6 will overlie a portion of the ring, such as at 1, and underlie the bead, as at 8, the Plaskon is well anchored with respect to the ring. Thus, even though the Plaskon may swell or shrink, it can never become detached from about the anchoring bead 5.

It is also to be noticed that the under surface of the Plaskon head tapers slightly near its outer under periphery, as at 9, to the horizontal under surface of the top, as at I0. I form the head in this manner so that the cloth II (Fig. 5) when gripped between the socket member I2 and its ring I will not be forced too far upwardly, which would tend to stretch the material about the ring and cause the cloth to pucker.

In other words, the topmost position of the cloth II is about in a plane with the top of the metal ring I and will thus lie snugly against the under` surface of the Plaskon disk 6 when the ring and socket member are attached.

In Fig. 5, there is shown a fragmentary portion of the cloth II and a socket member I2, which latter is provided with the prongs I3, which are to be gripped within the ring member. The socket member is disclosed in detail in the parental application heretofore mentioned.

Briefly, it consists of a circular metal plate having the prongs I3, the depressed portions I4 of the metal, the spring lingers I5, and the guards I6, the spring ngers I5v being adapted to grip the male member Y(not shown) of the socket. When the socket member of the snap fastener is being attached, the prongs I3 will pierce the cloth I I and impinge on the under surface of the overhanging wall 2 of the ring I and be bent to the position as shown in Fig. 5 to thus rmly hold the socket and its ring to the cloth.

plastic head may be greater in diameter or of greater thickness than show-n in` the drawing, if

found desirable.

Having thus described my invention, what I claim as new and desire to secure by Letters-l'rate` ent is:

1. In a socket for a snapV fastener, a clamping ringfhaving. an upper outwardlyand' downward# ly 'overhanging wall; anintegrallower peripheral rim spaced beneath saidwall andstopping short of' the periphery of`saidiwa1l to thereby form a space for the prongs ofa socket member, a plastic head extending over the center of. said ring, inner peripheralprojecting means .formed at' the topA offsaid ring, and the saidplastic head anfchoredin position'by. said` aforementionedimeans.

22 Aclamping ring, for "a snap fastener socket, said ring having a lower horizontally extending rim and a spaced,` outwardly and downwardly overhanging wallandlthe space between the said rimandsaidlwall adapted tolreceive the prongs of a snap fastener socket, aplastic head on said ring and extendingslightlybelow. the top surface Finally, it will aise be understoodr thatlthef of said ring and also overhanging the upper inner peripheral surface of the said ring, and

inner peripheral anchoring means formed inl tegral with the ring and embedded within said plastic head to hold the same tightly in position.

3.v A clamping. ring for afsnapfastener socket,

said ring having a horizontally outwardly extending lower peripheral rm and an upper downwardly extending overhanging Wall to thereby provide a receptive space for the prongs of a socket member, the ring provided with Ian upper inner peripheral. integral bead, a head on said ring and thel under surface of the head tapering downwardly to aplane beneath said bead, the outer upper peripheral edge of the head overlying said; bead whereby'th'e head is anchored to said ring: and the upperinner surface of the head being substantially in a horizontal plane with said bead;

4. Aclamping ring for asnap fastener socket, said. ring' having spaced" outwardly extending rims; oneof which is'longerfthan the' other, to thereby` provide 'ai' directing' wall' andi a; receptive space for thet'prongs oia'socket' member, a' plastic head" 'onsaid ring; means' formed' on' the inner peripheralsuifaceof Vthe ring' for interlocking with and anchoring the said' headtightly within the ring'and the .plastichead being thickest near its outer'peripheral' edge.

5. A plastic head having a metal ring' emb'edd'edtherein: and' the saidj ring provided.` with,

an' overhangingl wall and aI` spaced underlying rim-,the said Wall" and'rim` projecting wbeyond the sidewalls ofthe' plastic head; and the saidspace between the Wall. and' the rimadaptedlto receive andhold the prongsY ofthe socket member of a snapiastener.
